Legal Representation

Those seeking a plant patent should be aware that they may prosecute their applications through the services of a registered patent attorney/agent. While the PTO will not help in the selection of an attorney/agent, one seeking a plant patent should select an attorney/agent who is registered to practice before the PTO.
The USPTO maintains a directory of registered patent attorneys and agents at http://www.uspto.gov/web/offices/dcom/olia/oed/roster/index.html.
